Eldest daughter [Henrietta] very ill.

CD enjoys Owen’s having had "a good setting down".

Thanks for memoir of her father [G. Jäger, Zum Andenken an Dr. C. F. von Gärtner (1851)] and engravings.

Declines gift of CFvG’s collection of hybrid plants. Suggests Kew Herbarium.

Responds to HGB’s critique of Origin [appended to German translation of Origin]. Comments on English reviews.

Discusses Charles Daubeny’s views on sexuality of plants [Rep. BAAS 30 (1860) pt 2: 109–10]. "There is no greater mystery in the whole world, as it seems to me, than the existence of sexes, – more especially since the discovery of Parthenogenesis."

Says apropos of the FitzRoy Bible incident [at Oxford BAAS meeting], "I think his mind is often on verge of insanity."

Confirms CGBD’s impression given in a letter to J. S. Henslow that CD in the Origin did not touch directly upon the final causes of sexuality, which CD considers one of the "profoundest mysteries in nature". CD is inclined to stress sexuality as the means of keeping forms constant and checking variation although he grants its role in the origination of varieties. [See 2869.]

Henrietta’s illness.

CD’s resort to [E. W. Lane’s] water-cure.

Other family news.

Asa Gray’s anonymous review.

"Intensely interested" in orchid homologies; like a "game of chess".

Asks whether crossing breeds of hive-bees is advantageous

and whether different pigeon breeds have different incubation periods.

Explains and apologises for the lack of detailed quotations in Origin.

On the Fraser’s Magazine review by Hopkins [see 2860] and the Quarterly Review article by Wilberforce ["Darwin’s Origin of species", 108 (1860): 225–64]. The course of opinion since Oxford BAAS meeting. Asa Gray.

Need for Natural History Review, but fears it will be a burden for THH and lessen his original work. His own problem with work: if he had other duties he would be able to do absolutely nothing in science.

Is puzzled what to think about the [Natural History] Review. Doubts that it is wise that JL and Huxley should give up time to it: "if it would stop your doing original work you ought not, even pro bono publico, undertake the new work".

Reports on Henrietta’s health.

The Quarterly Review [108 (1860): 255–64] quizzes CD "capitally" and he read it with thorough enjoyment.

CD’s reaction to review of the Origin [by Samuel Wilberforce] in Quarterly Review [see 2881].

Greatly praises AG’s discussion of Origin in Proc. Am. Acad. Arts & Sci. [4 (1860): 411–15; 424–6].

Mentions other reviews of Origin; believes the BAAS meeting at Oxford greatly advanced the subject. Has heard his views are gaining ground in Germany.

CD mistaken, in Origin, p. 73, in saying that only humble-bees visit red clover.

Asa Gray’s articles in Proceedings of the American Academy of Arts and Sciences [10 Apr 1860] excellent; considering asking Athenæum to reprint them.

Thanks CH for correction of blunder in Origin about hive-bees sucking clover: "a greater kindness than a new fact".

Casual observations on Drosera.

Wants to know author of good review of Origin in London Review [& Wkly J. Polit. 1 (1860): 11–12, 32–3, 58–9].

Athenæum will reprint Gray’s discussion.

Comments on BAAS meeting: "our side seems to have got on very well". Asa Gray, too, is fighting nobly.

Comments on review [by Samuel Wilberforce] in the Quarterly [Rev. 108 (1860): 225–64].

Mentions a favourable review in the London Review.

Wonders if German translation [of the Origin] by Bronn has drawn attention to the subject.

The Natural History Review to be edited by Huxley and others.

Expects CL’s book [Antiquity of man (1863)] to be a bombshell.

Has been able to do nothing in science of late due to illness [of Henrietta].

When JDD reads Origin, CD knows he will be opposed to it, but he will be liberal and philosophical, which is more than he can say for his English opponents.

Has not yet seen L. Agassiz’s attack, but in principle avoids answering.

No one understands Origin so well as Asa Gray.

At BAAS meeting at Oxford, CD’s side seems almost to have got the best of the battle.

Thanks for information on pigeon hatching

and on drones.

Believes occasional crosses indispensable.

Though his book [Origin] has been abused and criticised as well as praised, its effect on good workers in science convinces him that in the main he is on the right road.

In reply to FW’s question, CD says his [CD’s] arguments are valid that all animals are descended from four or five primordial forms; analogy and weak reasons go to show they have descended from some single prototype.
